Question

Q2. The angles of a quarilateral are in the ratio 2:3:5:8. Find the fourth angle​

Answer 1

Answer:

160

Step-by-step explanation:

sum of all angles are360

let angle be x and add all ratios divide by 360 and multiply by 8

Answer 2

Step-by-step explanation:

let the each angle be x degree

a/q

sum of all angles of quadrilateral=360°

Angle A +B+C+D=360°

2x+3x+5x+8x=360°

18x=360°

x=360°/18

x=20°

therefore 4th angle=8x=8*20=160°
